All black spots on the face are not moles. It could be freckles,Lentigens, melasma
or post inflammatory hyper pigmentation (caused by primary problems like acne
, scratch mark or an injury
to the skin).
The treatment and results in all the different types vary. Hence it is first important to diagnose the cause and then treat it accordingly.
I would suggest a visit to a dermatologist
for getting the skin lesions diagnosed first.
1)Use a sunscreen whenever you step out of the house/office
2) Was your face with soap and water atleast 2 times/day
3) Avoid vigorous rubbing and wiping your face.
4) Drink plenty of water and have a nutritious diet including vegetables and fruits.
Once we know what you actually have, treating it gets easier and effective !!!!
